乙烯利是七十年代化学合成的植物内源激素。它能调节植物生理生化过程,加速器官衰老、脱落和促进农作物早熟增产。在棉花生产上它是克服低温阴雨和棉花贪青迟熟造成减产的一项行之有效的新方法。近几年来,全国各地试验认为,合理应用乙烯利,能够加速棉铃发育,提早成熟,而且吐絮集中、通畅,霜前花和优质花明显增多,皮棉品级提高。 1977年在省农业局和清江市农药厂、上海彭浦化工厂的支持下,我们着重对抗病陆地棉和海岛长绒棉进行乙烯利催熟试验,并在站内外200多亩棉田进行催熟示范试验,获得了初步成效,现把试验结果总结如下:
Ethephon is a plant endogenous hormones chemically synthesized in the seventies. It can regulate plant physiological and biochemical processes, accelerate organ aging, shedding and promote crop yield. In cotton production, it is a new and effective method to overcome the low temperature rainy season and the cotton cut-off caused by late ripening. In recent years, trials all over the country believe that the rational use of ethephon can accelerate the development of cotton bolls and prematurely mature. Moreover, the bolls are concentrated and unobstructed, the flowers and quality flowers before frost are obviously increased, and the quality of lint cotton is improved. In 1977, with the support of the Provincial Department of Agriculture and Qingjiang Pesticide Factory and Shanghai Pengpu Chemical Factory, we focused on the ethephon ripening test against the disease of Upland cotton and island long staple cotton, and ripened in 200 mu of cotton fields inside and outside the station Demonstration test, obtained initial results, the test results are summarized as follows:
